VMware Tools Memory Leak Issues

Products

• VMware vSphere ESXi

Issue/Introduction

Over an extended time period, the vmtoolsd process is seen to use increasing amounts of guest memory when the vSphere APIs ListGuestAliases and ListGuestMappedAliases are used.

Resolution

To resolve this issue:

Upgrade to the latest version of VMware Tools
Generally, the versions 11.0.1 and later of VMware Tools and open-vm-tools regardless of the OS include fixes. For Tar Installer or OSPs for Linux versions that do not ship with open-vm-tools, it is recommended to upgrade VMware Tools to version 10.3.21 or later.

For open-vm-tools, OS vendors have also included fixes in their latest package updates outside of VMware Tools' release schedule. The following table shows the package versions that include fixes for the memory leaks:
